One of the most eagerly anticipated tech events of the year is finally upon us. While all the attention is set on the tenth anniversary iPhone or the iPhone X, Apple is set to announce a host of products today including the Apple Watch 3, an Apple TV with 4K support, updated versions of the iPhone 7 and 7 Plus and more.

The much talked about event is set to start at 10am PDT (10:30PM for India) and will be held at the Steve Jobs Theatre in Apple's brand new Apple Park campus. You can catch the event live by heading over to Apple's official website via any iOS device, Mac laptop/desktop (using Safari) or the Edge browser in Windows.

This year's event is going to be extra special as it marks the tenth anniversary of the iPhone. Apple is reportedly leaving no stone un-turned to make this occasion noteworthy. For the first time, Apple will be launching three new iPhones at the same time. Amongst them will be the tenth anniversary iPhone X.

Here is a look at what Apple is expected to announce at their most exciting launch event yet:

iPhone X

With the tenth anniversary iPhone or the iPhone X, Apple is set to introduce its most drastic update to the iPhone line yet. In the offing is a radical re-design, an OLED screen, AR based features, updated cameras and more.

The iPhone X is expected to feature a striking bezel-less design with an all glass back, a polished stainless steel metal frame and a vertical rear dual camera setup. The iconic home button, once a staple of the iPhone line-up, is set to be axed.

In the home button's place, Apple is expected to introduce a new feature in the iPhone X's software called 'Function Area' which will occupy the bottom of the smartphone's display at all times and change dynamically based on which apps are being used.

After years of sticking with IPS LCD panels, Apple is finally making the transition to OLED with the iPhone X. The iOS 11 general master points towards the iPhone X coming with a 5.8-inch TrueTone OLED display with a resolution of 1125x2436.

OLED panels have better contrast and punchier colors than LCD displays and are used by Android competitors like the Google Pixel and Samsung Galaxy S8. The True Tone display, a technology which was first seen on the 9.7-inch iPad Pro, changes its color temperature and hue depending on the surroundings in order to reduce eye strain.

With the iPhone X, Apple is reportedly ditching the Touch ID fingerprint sensor and bringing 3D face recognition in its place. Apple's Face ID will reportedly not only allow users to unlock the device but also authenticate payments through Apple Pay and launch secure applications. It is also said to capture more data and be more secure than TouchID.

The iPhone X will also come with an updated dual camera setup at the rear with an improved image sensor, a better telephoto lens (than the iPhone 7 Plus) and 3D sensing capabilities. There are various reports doing the rounds of the internet which also claim that the tenth anniversary iPhone will come with a rear-facing 3D sensor to help with autofocus and augmented reality (AR) features.

The iPhone X will be powered by an all new A11 processor which will undoubtedly be Apple's most powerful and efficient chipset to date. It is set to come with 3GB of RAM, IP68 waterproofing, wireless charging and an updated 3D touch module. The smartphone is expected to be offered in three colour variants at launch - White, Gold and Black.

iPhone 8 and iPhone 8 Plus

While the iPhone X will undoubtedly be the star of tonight's show, two other iPhones are also expected to be announced. The iPhone 8 and iPhone 8 Plus are set to be updated versions of the iPhone 7 and 7 Plus respectively.

The two smartphone are expected to look extremely similar to the current generation of iPhones with one possible exception - they might come with all glass backs in order to accommodate wireless charging. The frame will still be made out of aluminum.

Even though the iPhone 8 and iPhone 8 Plus are not set to get a massive redesign, they are expected to come with updated cameras, a faster processor in the form of the A11, improved battery life and as mentioned above wireless charging support. The iPhone 8 is expected to come with 2GB of RAM, while the iPhone 8 Plus looks set to come with 3GB of RAM.

Apple Watch 3

While the rumour mill has been a bit quiet regarding Apple's smartwatch, the company is expected to unveil the third generation of the Apple Watch at today's event. There have been multiple reports this week claiming that the Apple Watch 3 will come with LTE capabilities and a design similar to the current generation Watch.

Users will reportedly be able to insert a SIM card into the Apple Watch 3 in order to send messages, browse the net, stream music and use apps without having to connect to an iPhone. Additionally, Apple is expected to tweak the software on the Watch with improvements to all core functions, including the Music and Workout app in particular, expected. It will also support peer to peer payments.

4K Apple TV

Apple is widely expected to announce a new generation of the Apple TV with 4K and HDR video support. The Apple TV has not received a significant update since 2015 and the fifth generation Apple TV is much anticipated by Apple fans. This new Apple TV is also expected to come with all new internals in order to power 4K video playback.

New AirPods

While not a lot is known about them at the moment, there also rumours that Apple might unveil the second generation AirPods at today's event. Apple announced their wireless earphones along with the iPhone 7 and iPhone 7 Plus last year.

AirPods are seen by many as a a part of Apple's effort to move towards a wireless world. Just like the iPhone 7 and 7 Plus, the iPhone X, iPhone 8 and iPhone 8 Plus are not expected to come with a 3.5mm headphone jack.

iOS 11, macOS High Sierra

Along with all the shiny new hardware, Apple will also announce the release dates of iOS 11 and macOS High Sierra, which were announced a few months ago at WWDC 2017. iOS 11 comes with a host of new features such as a redesigned control centre, an all new App Store, a new design ethos for all first party Apple applications, Siri translations, a file manager and more.

Apple might also announce a few new iPhone X only features of iOS 11 such as the aforementioned 'Function Area' which had been kept under wraps during the WWDC announcement back in June.

macOS High Sierra is an iterative update that promises to be safer and faster than Sierra. A major focus of High Sierra is on helping applications use less file space than ever. This is majorly achieved through Apple's new file system which replaces the age old Hierarchical File System found in previous versions of OS X.

macOS High Sierra also brings with it performance updates to Safari, a new Photos app, a new version of Apple's graphics technology called Metal 2 and a new version of the Mail app which takes 35 percent less space than before.
